Question about court date.?

My boyfriend was caught doing a doughnut in a Target parking lot. He has never recieved a ticket or any violation/been pulled over since he got his License 6 years ago. The ticket was for wreckless driving & exhibtion of speed. What should he plea guilty or not guilty or no contest? Should he get a public defender, take it to trial, or what? Since it happened on a Target parking lot wouldn't it be on private property and cops don't have jurisdiction there?
